Kelvin waves and the singular modes of the Lamb-Oseen vortex Columnar vortices are known to support a family of waves initially discovered by Lord Kelvin (1880) in the case of the Rankine vortex model. This paper pre... FABRE,D. - 《Journal of Fluid Mechanics》 被引量: 157发表: 2006年...

The displacement pattern arising from the decay of a two-dimensional Lamb-Oseen vortex in a Newtonian fluid can be closely modeled by the closed-form expression presented here. This formula enables Lamb-Oseen vortex simulation orders of magnitude faster than can be accomplished using finite-element ...

The linear response of the Lamb–Oseen vortex to stochastic forcing can be decomposed in relation to the azimuthal symmetry of the perturbation given by the azimuthal wavenumberm. In the axisymmetric casem= 0, we find that the response is characterized by the generation of vortex rings at the ...
The optimal response in the Lamb-Oseen vortex is studied by considering the harmonically forced problem with frequency 蠅. High variance levels are sustained in these systems under periodic forcing. In the axisymmetric case n=0, the response is the largest when the input frequency is zero. When...
Lamb–Oseen vortexOptimal responsePeriodic forcingThe level of the response energy is compared to that without forcing. Different azimuthal modes are studied and compared. The reason of the location of peaks for helical modes is presented. The non-smoothness of curves for helical modes is explained...
The article "Trapped free surface waves for a Lamb鈥揙seen vortex flow" in the Journal of Fluid Mechanics delves into the behavior of surface waves within a rotating fluid vortex. It identifies two types of modes, radiating and trapped, with the transition between them dependent on...
external pulsationThe effect of external pulsation on a pair of stationary Lamb–Oseen vortices of equal strength has been analyzed to investigate kinematic behavior of a fluid particle. The assumption of vortices beingdoi:10.1007/s12046-017-0620-1S Ananth Pai...
